Abstract:
Objective To explore the characteristics of field potentials within vestibular nuclei evoked by electrical stimulus.Methods Double silver electrodes were placed on the surface of the round window.The vestibular nuclei field potential was recorded under the condition of electrical stimulus.Results The field potential consists of a negative wave(N1),the threshold was 0.59?0.07 mA or 0.90?0.50 V,the latency of N1 peak was 1.20?0.13 ms.When double stimuli were applied,no response was noted.The second stimulus or the response was small if the time interval was less than 4 ms.Conclusion Evoked vestibular nuclei potential can be obtained by peripheral labyrinth electrical stimulus,which is quite stable.
